Hydrogen gas is filled in a 224 ml glass container at 0 degree celcius and 1 atmospheric pressure. what are the number of molecule of hydrogen in the container? ?

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
